The authors consider the problem of patency of ductus arteriosus (P.D.A.) in pre-term infants. On the basis of their own experience and reviewing international literature they discuss about mechanisms maintaining open ductus, incidence, methods of diagnosis, clinical findings and indomethacin therapy. Finally current indications for indomethacin use are discussed.
We have carried out an epidemiological-statistical study about congenital heart disease on 33.245 live-born infants in Parma from 1972 to 1980. 327 newborns with congenital heart disease were found; the incidence was 9,8/1000 live-born. The lowest value was 5,8/1000 live-born in 1972, the highest was 14,5/1000 live-born in 1977. In the majority of cases diagnosis was only clinical VSD, PDA, ecc.), whereas in the more complex cardiac malformations and in patients with severe congestive heart failure diagnosis was confirmed at cardiac catheterization and at surgery. In 60 cases diagnosis was confirmed also at autopsy. The congenital heart disease most frequently observed was VSD (33%), followed by PDA (13,4%) and TGA (8,8%), ecc. Clinical status at 1 year of age in all patients was evaluated. The Authors think that infant cardiac program is necessary to improve the results on congenital heart disease control.
